-Application filed June 21,

To all whom it may concern: a Beit known that L'Jnssn A. CLIFTON, a citizen'of the United States, and a resident of Orangebur in the county of Orangeburg andState of outh Carolina, have invented certain new and useful 1m rovements in Wax Melting Machine and eal Maker, of which the following is a specification.

My invention is an improvementin wax sealers" andhas for its object to provide means for {containing a quantity ofwax, and having means for deliveringsmall quantities of the wax whendesired onto the object tobe sealed','as for instance a package, and having other means operable at will for heatingthe wax to melt the same, the

said sealer carrying a seal for making an impress on the wax delivered onto the object to be sealed.

Figure 1 is a vertical sectionthrough the improved sealer,

Fig. 2 is atop plan forthewax. m t

Fig. 3 isa bottom plan view of the seal. In the present embodiment of the invention, al'jacketed magazine orcontainer is provided, composed of an inner vessel or chamber 1 and an outer vessel or chamber 2. Theltop of-the inner chamber is open as shown, and the bottom is funnel shaped or tapering and has a deliveryopening 6.

At its top the inner chamber has an outwardly extending" flange 3, which by its engagement with the outer chamber wall spaces thelchambers apart. The outer chamber 2 has at its top an inwardly tapering flange view of the container or'collar 4, forming 'a tapered or sloping top and a cylindrical cover 5 fits within the the flange, to close the top of the outer chamber and of the container.

The lower end of the chamber 2is also open, and a nipple 6 is arranged in the opening, encircling the delivery opening 6 of the inner, chamber, which. delivers through the nipple Thenippleis normally closed by a spring closing plate 7, which is mounted to swing through a slot the nipple, and

Aresistance or heating wire 9 is arranged this closing plate is connectedto a seal carrying ring .8 to be "presentlv described.

in spiral form between the tapering portions of thetwo chambers, and the terminals of the coilindicated' at 10 and 11 are connected with a suitable source of electrical energy, as for instance, a lighting circuit. The terminal 10 of the coil is connected with a spring contact plate 12 secured at one end as at 12 within a hollow or tubular handle 13 which extends laterally from the upper portion of the chamber 2, and the terminal 11' is connected with a suitable socket which 1 may engage a'lighting fixture, as for instance a lamp socket. Another wire 14: con nects the socket with a sliding contact member 15 mounted. to slide on the handle 13, and having a contact member .15 adapted to contactwith thefree end of the member or plate 12, to close thecircuit through the wire9.- 1

Referring to Fig. 1 it will be noted that the handle 13 is slotted at the plate 12, so that the contact member 15 on the sliding contact 15 may contact with the plate 12" to close the circuit. The free end of the plate 12 is curved downwardly: as shown to facilitate engagement and disengagement of the parts. It will be obvious that insteadof the sliding contactswitch 12-15, the usual snap switch of the fixture might be utilized.

A bell crank 16 is pivoted to a bracketl'? depending from the handle 13,and one arm of the bell crank carries the ring 8 before mentioned. The other arm or the bell crank has a finger-piece 18 in the form of a loop ranged thatthey are spaced on each side of the closing plate 7. a In orderto insure the positive delivery of the melted wax trom the container, a

plunger or piston 22 is arranged within the cylindrical cover 5, and this plunger has a stem 23 whichextends upwardly through a central opening in the cover. A lever 2 1 is pivoted intermediate its ends at a support extending upwardly from the handle and one end of the lever is forked,and the stem 23 extends between the arms of the fork, and has a ring 23 above the said arms. The other end of the lever is connected by a link 26 with that arm of the bell crank which carries the fingerpiece 18, said arm having a series of perforations or openings so that the lower angularlybent end of the link 26 may be adjusted therein to regulate the stroke of the plunger or piston 22 and thus the degree oicompression and quantity of waxexpelled; The arrangement is such that when the bell crank is swung to'open the nipple 6, by withdrawing the closing plate 7, the plunger 22 will be pushed downwardfly, compressing the air before the wax 1 m the container 1, and positively discharging apredetermined quantity of wax. The cover 5 has a pin holeopening 27, which may be closed by a cover plate 28 pivoted to the cover to control the action of the plunger and air within the-chamber and jacketed magazine or container 1,; and the discharge of the wax from the latter.

The cylindrical coverl 5 forms a cylinder in which the plunger or'piston 22 operates,

and the bottom of the cylinder and the plunger are provided with check valves 30 'and 3l to controlth'e pumping or, expelling action. When the'plunger moves down, the valve 30 is open andv the valve lclosed, the airubeing forced ahead" of the plunger or piston and into the chamberl and against the wax to expel the same. When the plunger moves up, the valve 30 is closed and the valve 31 is open allowing the pressure to be released, depending upon the position of the cover plate 28. 7 V

i In operation, when it is desiredto seal a package for instance, the package is placed beneath the nipple 6, the circuit is closed by means'ot the sliding contact 15, and the bell crank is operated to open the container. The same movement depresses the plunger, .and forces a quantity of air from the cylindrical cover into the jacketed chamber. Thus a "qnantity of wax will be positively expelled from thechamber. The handle 13 is of insulating material in practice.
